"It is with great sadness that myself and my family announce the unexpected passing of our son and brother, Chris Cattrall," the actress captioned a photo of herself with Chris on Instagram and Twitter. "At this time we ask for privacy but we want to thank you all on social media for your outpouring of love and support in this trying time."

The Emmy winner, who played writer Carrie Bradshaw on the hit series, told host Andy Cohen it had been a "privilege" acting with Cattrall for so many years, and hoped the time they spent working on the beloved show together "eclipses anything that’s been recently spoken."
